Processor / SMD heatsink for BGA/PGA/LGA boards

PCB heatsink for high-performance electronic components

On a printed circuit board, semiconductor components such as voltage regulators, transistors, microprocessors and power converters typically generate a lot of heat that needs to be dissipated. Otherwise, overheating can damage the component or even the entire printed circuit board. With a wide range of heat sink solutions, heat conducting pads and fans for active cooling, EKL offers you powerful and cost-optimised PCB heat sinks. In some cases, the PCB itself can also be used as a heat sink by designing it in such a way that it efficiently distributes and dissipates the heat. Contact us as early as the design phase of a PCB to optimise the integration of heat dissipation into your PCB layout. Efficient cooling contributes significantly to the optimum function and longevity of your electronic assembly!

With over 29 years of experience in cooling high-performance electronic assemblies, we are your reliable partner. Our engineers are guaranteed to find the optimum heat sink for your circuit boards within the available installation space and budget.

The right PCB heat sink for the circuit board for every standard

The designation "TO" stands for "Transistor Outline" and the number indicates the specific shape and size of the enclosure:
  • TO 220 heat sinks for enclosures with cooling fins: These enclosures are particularly important for heat dissipation in electronic components that process higher power levels. For effective cooling, these components often have to be mounted on a heat sink/PCB cooler, with an insulating plate placed between the cooling fin and the heat sink to ensure electrical insulation.
  • TO 218 heat sink for semiconductor packages, often used in electronics for power components such as transistors. It is known for its ability to handle high currents and is often used as PCB heatsinks that require efficient heat dissipation. The TO-218 packages are designed to be mounted on heat sinks to dissipate the heat generated by operation. This is crucial to ensure the reliability and longevity of the electronic components.
  • TO 05 heat sinks for packages of small semiconductors such as transistors: They are known for their round metal can shape, often with a flat area for mounting and heat dissipation. The PCB Heat Dink design of these packages allows for efficient heat dissipation and protection for the component, making it useful for applications where reliability and longevity are important.
  • TO 18 heat sinks for transistor metal housings, which are known for their robustness. They are often used for components that have to withstand higher loads. There are also variants that are used for diodes, photodiodes and LEDs, which can only have two connections.
  • SMD heat sinks for surface-mounted devices: electronic components that have been developed for surface mounting. Unlike traditional through-hole mounted components that use wire leads, SMDs have solderable pads that are soldered directly to PCBs. This technology allows for a more compact and efficient design of electronic devices as it takes up less space and allows for double-sided assembly of the PCB. EKL heat sinks for SMD are perfectly designed for this.
  • DPAK/TO252 heat sinks for semiconductor housings of transistors and diodes: The "DPAK" stands for "Discrete Package" and is known for its compact size and its ability to efficiently dissipate heat. DPAK components are usually rectangular with a flat bottom that is soldered to a printed circuit board to ensure a good thermal connection.
  • D2PAK/TO263 heat sinks for semiconductor device package types commonly used for transistors and MOSFETs. This type of component is known for its ability to handle higher power, making it ideal for applications that require good heat dissipation.
  • D3PAK/TO-268 heat sinks for even larger package types.
